Abstract :
A description is given of under relaxation techniques for obtaining stable convergence in network simulation. The virtual state relaxation (VSR) technique is presented, and under relaxation techniques developed from the VSR method are then considered. These techniques are utilized in the simulation program DESIRE. The authors apply the modified under relaxation to the simulation of nonlinear resistive networks, including bipolar transistor circuits, and verify stable convergence
